Achilles Tendonitis/Tendinopathy and Needling

Achilles pain. You can’t live with it and you can’t live with it. Can needling help? The obvious answer is yes, but there is more as well.

There appears to be sufficient data to support the use of needling for achilles tendon problems . Perhaps it is the “reorganization” of collagen that makes it effective or a blood flow/vascularization phenomenon. The mechanism probably has something to do with pain and the reticular formation sending information down the cord via the lateral cell column (intermediolateral cell nucleus) or pain (nociceptive) afferents sending a collateral in the spinal cord to the dysfunctional muscle, affecting the alpha receptors and causing vasodilation. 

Loss of ankle dorsiflexion is a common factor that seems to contribute to achilles tendinopathies . It would seem that improving ankle rocker would be most helpful. In at least one study, needling restored ankle function and in another it improved strength. 

And don’t forget to go north of the lower leg/foot/ankle complex. The gluteus medius can many times the culprit as well. During running, the gluteus medius usually fires before heel strike, most likely to stabilize the hip and the pelvis. In runners with Achilles Tendonitis, its firing is delayed which may affect the kinematics of knee and ankle resulting in rear foot inversion. Perhaps the delayed action of the gluteus medius allows an adductory moment of the pelvis, moving the center of gravity medially. This could conceivably place additional stress on the achilles tendon (via the lateral gastroc) to create more eversion of the foot from midstance onward.

Similarly, in runners with achilles tendoinopathy, the gluteus maximus does not fire as long and activation is delayed. The glute max should be the primary hip extensor and decreased hip extension might be compensated by an increased ankle plantarflexion which could potentially increase the load on the Achilles tendon. 

So, in short, yes, needling will probably help, for these reasons and probably many more. Make sure to needle all the dysfunctional muscles up the chain, beginning at the foot and moving rostrally.

Take good look at these gals. The gal on the left (in blue) looks like she has a level pelvis, but look at the upper body. She’s leaning to the left and has a great deal of torso rotation backward. One of the clues is the abduction of her left arm. Also note how her right arm crosses across her body. We wonder how she looks in right foot stance.

The gal on the left (in red) has a subtle dip of the right side of her pelvis and also has over rotation of her upper body. Her right on crossing the body is a good reason to believe she will have a crossover gait if viewed from straight on.

While both of these gals may have adequate strength, we question how much endurance they have as well as available rotation in the hips and lumbar spine.

This is an excellent, referenced review of some of the current literature and controversy of strength and injury risk. A good read and certainly worth your time to get caught up on what’s current. We would love to see you study on endurance and injury risk.

“While muscle strength may improve tolerance of loads during running, another reason for inconsistencies in the reported relationships between strength and injury risk may be that strength is typically assessed isometrically. It’s unclear how much of an influence peak isometric strength has on the dynamic task of running, and specifically on prolonged running in the presence of muscular fatigue. Schmitz et al found that, while isometric hip strength values were similar between novice and experienced runners, hip internal rotation motion during running was higher in the novice runners, suggesting isometric strength may not correlate strongly with muscular control and kinematics during running.”

Do quarter squats transfer best to sprinting?

We have always said that exercises are specific as to the type of exercise (isometric, isotonic, isokinetic) as well as the speed of exercise. And this backs that up, with a surprise:

Unexpectedly, QUARTER produced superior gains in both vertical jump height and 40-yard sprint running times, compared with both HALF and FULL. give it a read, especially the vertical jump section..

Those Multifidi

The multifidi are important proprioceptive sentinels for the low back, as well as the rest of the body, for virtually every activity you do weight bearing, including gait. They are implicated in many instances of low back pain, especially folks with flexion or extension intolerance, since their fiber orientation and thus mechanical advantage (or disadvantage) is dependent upon whether or not you are maintaining a normal lumbar lordosis.

Modalities which boost their function are an excellent adjunct to the rehabilitation process. Since they are not under volitional control (go ahead, try and contract your L2/L3 multifidus), they are innervated by the vestibulospinal tract and we must use proprioceptive work to engage them. Dry Needling is one modality that can help them to become functional again.

RESULTS and CONCLUSION:
“Significant difference was found in the percentage of change of muscle activation post needling between groups on the right side at level L4-5. A slight increase in the percentage of muscle activity, post procedure was observed in the dry needling group compared with the control group, although not significant in other segments examined. An improvement of back muscle function following dry needling procedure in healthy individuals was found. This implies that dry needling might stimulate motor nerve fibers and as such increase muscle activity.”

Yay for the lift, spread and reach exercise!

Toe spreads and squeezes are aimed at strengthening specific intrinsic foot muscles—the dorsal and plantar interrosei, according to Irene S. Davis, PhD, PT, director of the Spaulding National Running Center and a professor in the Department of Physical Medicine and Rehabilitation at Harvard Medical School in Boston. Doming or foot shortening exercises contract most of the muscles on the plantar side of the foot, and help to strengthen the abductor hallucis muscle

How are your hammy’s?

Another tool for you, in addition to making sure the gluten are on line, to improve ankle rocker and hip extension.

“This study concludes that neural mobilization techniques are a useful adjunct to static stretching, without any risk of adverse events or injuries. Athletes or trainers can consider using one or both types of neural mobilization techniques to enhance muscular flexibility. Dosage of the neural mobilization as well as the proposed working mechanism behind the increase in hamstring flexibility can be found in the full text of the article.”
